一般的数据量。

导出excel 例子代码如下，主要思路是mysql 读取数据到php 变量保存，整理成excel 开头格式的字符串，写入文件，保存为 xxx.csv 文件， excel 文件的特性，必须 是GBK, 使用 iconv 转义 字符编码 iconv("utf-8","GBK//TRANSLIT",$csvStr); A 如果内容少 excel 内容直接 告知文件头信息，然后 header("Content-type:text/csv"); header("Content-Disposition:attachment;filename=".$fileNameCsv); echo 出来就可以。 记得需要exit。断掉。

B 文件数据比较多，需要分页获取数据，写入 文件，然后header('Location://http://xxx.xxx.xxx/xx.csv'); 分页是否截至，需要 do{}while(); 如果是多台服务器，那么需要借助 redis key ,存储 文件名，还有状态 （0，没有，1有文件了。过期时间为一天），然后数据就可以不用担心判断不出来 ，是否已经后台生成了。 这个时候定时脚本没3分钟执行一次，避免多任务堆积，吃掉内存，服务挂机。使用 exec('ps -efH|grep "'.basename(FILE).'"', $output); if(count($output) > 3) { //类似守护进程，保证只运行1个此进程 print_r($output); exit; } 判断当前是否已经执行过，需要等待上次执行后，这次才能执行。这个程序导出 23w ，数据大概是 1小时。业务不需要太准确数据，延时几小时可以接受。当键值24小时过期，那么通过键值判断是否已经生成问见我，新文件替换老文件

然后下载文件
